vApplication filed February 18, 1889. Serial No. 300,233. (No model.)

To all whom t may concern.-

Be it known that I, JOHN XV. HYATT, a citi- Zen of the United States, residing at Newark, Essex county, New Jersey, have invented cer- 5 tain new and useful Improvements in Juice- Extractors, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to apparatus for exro tracting from disintegrated vegetable materials their liquid or soluble constituents by contlnihg the material operated upon in a chamber, herein called a compression-chamber, and therein subjecting it to compression between a pervious plunger, herein called a compressing-screen, and a body of liquid, herein called a liquid anvil, contained in a reservoir which forms a closed continuation of the said compression-chamber.

adapted for the desired purpose illustrate one form in which a horiZontally-reciprocating compressing-screen is employed and another form in which a vertically-reciprocating com- 2 5 pressing-screen is employed, the principle of operation being the same in both cases.

A The drawings are as follows: Figures l, 2, and 3 are respectively a top view, alongitudinal vertical section, and an end elevation, showing a form of apparatus in which there is employed a horizontal compression-chamber, one end of which is connected with an an vil-clianibei-,which is arranged beneath the compression-chamber and is provided at each 3 5 end with a tight-fitting removable door. Fig. 4 is a top view showing the portion ol' the end of the compression-chamber in which the compressing-screen reciprocates, the opposite `end of the compression-chamber being represented as broken away. Fig. 5 is a longitudinal section taken through the plane indicated by the line a: on Fig. 4f. Fig. 6 is a transA verse section taken through the plane indicated by the line y y on Fig. 5. Fig. 7 is a central Vertical section of a form of apparatus employing a Vertical compression-chamber arranged at the top of a bottle-shaped anvilchamber.

Referring to the drawings, it will be seen 5o that Figs. l, 2, and 3 representacompressing The accompanying `drawings of apparatus apparatus composed of a horizontal cylinder A, one end of which is connected by the downwardly-extending iiaring goose-neck a with the cylindrically-shaped anvil-chamberB, provided With the tight-fitting removable heads C C, which are held againstthe ends of the cylinder B by means of the longitudinal holt D,

A service-pipe E is provided for supplying the chamber B with the liquid which is to 6o serve as the liquid anvil.

In the end of the cylinder A opposite that connected with the anvil-chamber B is the plunger F, to which reciprocating motion is imparted by means of the double link G from the crank H of the rotating drivingwheel I. The working end of the plunger has seated upon it a series of sieves or strainers F', as symbolically represented in cross-section in Fig. 5. In the rear of the 7o sieves the longitudinal passages f in the plunger aiford paths of escape for the liquid products of compression into the transverse channel f', and thence into the longitudinal channel f2, found in the plunger F. The liquid products of compression are thus conducted to the semi-cylindrical extension of the cylinder A, which constitutes the discharging-trough J, from the end of which they fall into a tank suitably placed to re- 8o ceive them.

The plunger F, provided with the passages described and with the strainers F', is made to perform the functions both of a compressor and of a screen, and is hence herein called the compressing-screen.

A feed-opening K is formed in the upper side of the cylinder A, through" which the masses of disintegrated material to be operated upon are fed into the lcylinder in front of` the compressing-screen. The portion of the cylinder A into which the disintegrated material fed through the feed-opening K is driven by the working-strokes of the compressing-screen constitutes the compressionchamber. I

In the form of apparatus represented in Fig. 7 the compression-chamber is a vertical cylinder A', erected upon the top of Athe bottle-shaped anvil-chamber B', which is proroo 1o f3 of the plunger drives into the upper end of the cylinder the charge of fiber which may have been fed into the hopper K'. The convergent- Walls of the hopper K' are perforated, as shown, and the perforated portion of the hopper is provided with a jacket J', to which is attached a discharge-pipej. The liquid products of compression compelled to exude'through the mass of compressed fiber and through the perforations in the plung'er at each downward or working stroke thereof flow into the jacket J', from which they are conducted by the pipe j to the receivingtank j'.

The anvil-chamber may be provided with a pressure-gage L and With a suitable reliefvalve M, as illustrated, for example, in Fig. 7.

In operation, in either of the forms of apparatus described, the masses of disintegrated material successively fed into the compression-chamber are by the working-strokes of the compression-screen compressed into a succession of wads, by the collection of which a plug is formed which closely fits the compression-chamber. This plug is supported against the thrust of the coimpressing-screen by the .iiuid composing the liquid anvil,against which it bears. A certain portion of this fluid is necessarily displaced as each successive Wad is added tothe plug, and as the plug is driven toward the anvil-chamber the displaced liquid is compelled to exude through the plug as its only avenue of escape. By being thus brought into enforced contact With the soluble constituents of the plug' the displaced liquid dissolves them, and at the same time drives before it any liquid which it finds already contained in the plug. As has been explained, the liquid'products 'of compression escape through the compressing-screen and are ultimately conducted into a suitable receiving-tank. material composing' the end of the plug to- Ward the liquid anvil falls into the anvilchamber, from which it is removed from time to time, as may be required, by opening or detaching the removable head C or door C', with which the anvil-chamber is provided. The machine will usually be brought to rest for this purpose, and afterthe exhausted material has been removed, the head C or door C' replaced, and the anvil-chamber again iilled With liquid the machine will again be set in motiony and the compressing operation resumed.

The gage L indicates the pressure in the anvil-chamber when the apparatus is at work,

The exhausted and it will hence be seen that the feeding of the material and the stroke of the plunger may be varied according to the indications of the gage, so as to produce any desired pressure, and that the valve M will serve as a safety-valve, which Will relieve the pressure if it becomes unduly excessive.

Apparatus of the character described is adapted for the extraction ofthe soluble constituents of comparatively dry substancessuch as hops and drugs-and also for the extraction of the soluble constituents and the natural juices of more moist material, such as apples, beets, sugar-cane, dac.

That is claimed as the invention isl. In an extracting apparatus, the combination, as herein set forth, of a reservoir for containinga body of liquid which is to serve as a liquid anvil, a compression-chamber forming the mouth of said reservoir, a compressing-screen, and means for reciprocating said compressing screen in said compressionchamber, as and for the purposes described.

2. In an extracting apparatus, the combination, as herein set forth, of a compressionchamber, a compressing-screen reciprocating therein, a feed-opening for the successive feeding into said compression-chamber of bodies of the material to be operated upon, and a reservoir forming a closed continuation of said com pression-chamber extending below lthe level thereof, as and for the purposes described.

3. In an extracting apparatus, the combination, as herein set forth, of a compressionchamber supplied intermittin gly With the material to be operated upon and having a feedopening in one side, a hopper applied to said feed-opening, a compressing-screen reciprocating' in said compression-chamber past the said feed-opening, and a reservoir connected with the discharge end of said compressionchamber and forming a closed continuation thereof, as and for the purposes described.

4. In an extracting apparatus, the combination, as herein set forth, of a compressionchamber, a compressing-screen reciprocating therein, and a reservoir connected with the discharge end of said compression-chamber and forming a continuation thereof of greater diameter than the diameter of said compression-chamber, as and for the purposes described. v

5. In an extracting apparatus, the combination, as herein set forth, of a compressionchamber, a compressing-screen reciprocatingA therein, a reservoir connected with the discharge end of said compression-chamber and forming a closed continuation of said compression-chamber, extending below the level thereof, and a tight-fitting removable door applied to said reservoir, .as and for the purposes described.

6. In an extracting apparatus, the combination, as herein set forth, of a compressionchamber, a compressing-screen reciprocating IIO therein, n reservoir connected with the dis-V for the purpose of imparting reciprocating motion thereto.

In testimony whereof I have hereunto Set 1o my hand in Iche presence of Jnwo subscribing Witnesses.
